Effects of carbontetrachloride and chenodeoxycholic acid on hepatic monooxygenase system, lipid peroxidation and some immunologic parameters in rats.

The effect of chenodeoxycholic acid on liver monooxygenase system, lipid peroxidation, lymphocyte proliferation, and immune complexes formation was studied in carbontetrachloride-treated rats. Chenodeoxycholic acid increased the content of both cytochrome P-450 and cytochrome b5 and the rate of aminopyrine N-demethylation in liver microsomal fractions. It also normalized lipid peroxidation in the liver and the proliferative activity of blood lymphocytes activated by phytohemagglutinin.
